NAME

udbp - USB Double Bulk Pipe driver

SYNOPSIS

To compile this driver into the kernel, place the following line in your
kernel configuration file:
deviceudbp
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
udbp_load="YES"

DESCRIPTION

The udbp driver provides support for host-to-host cables that contain at
least two bulk pipes (one for each direction), for example the EzLink
cable and the NetChip 1080 chip.
It requires netgraph(4) to be available. This can be done either by
adding optionsNETGRAPH to your kernel configuration file, or
alternatively loading netgraph(4) as a module, either from
/boot/loader.conf or from the command line, before the udbp module.

EXAMPLES

options NETGRAPH
device udbp
Add the udbp driver to the kernel.
kldload netgraph
kldload udbp
Load the netgraph(4) module and then the udbp driver.
ngctl mkpeer udbp0: iface data inet
ifconfig ng0 10.0.0.1 10.0.0.2
Create a new network interface node and connect its inet hook to the data
hook of the udbp node. ifconfig(8) configures the resulting network
interface ng0 with a local IP address of 10.0.0.1 and a remote IP address
of 10.0.0.2. On the remote host, the two IP addresses should of course
be reversed.
